A Raspberry Pi Zero based DIY Scientific Calculator: WarpPi @cavallium @Raspberry_Pi
A neat project posted by Tom Nardi on Hackaday. Andrea Cavalli has built a scientific calculator based on the Raspberry Pi. The PCB hooks right up to the GPIO pins of the internal Raspberry Pi Zero, making interfacing with the dome switch keyboard very easy. The case, including the buttons, is entirely 3D printed.
The project was started before the NumWorks calculator according to Cavalli in the articles comments. While similar, they really are different concepts. NumWorks uses MicroPython and aims for compatibility with test taking requirements. WarpPI can use the power of the Raspberry Pi to do many things if desired. It currently has a very good algebraic calculator program in development.
